What does this mean?
Your email is a bit weird since it says Canada Visa Application Centre to Canada Visa Application Centre
Is your visa approved and have you submitted your passport to VAC? Cause the next step should be between Canada Visa Application Centre and IRCC.
Based on my experience I got the following emails
1. Once I submitted my passport... Canada Visa Application Centre receives your passport it will be dispatched to IRCC.
2. IRCC will process (put the stamp) on the passport.
3. An envelope of your decision that has been processed has been sent from the IRCC office, on the date to the Canadian Visa Application Center . At this point means the passport is ready for collection
4. Your processed decision envelope has been collected from the Canada Visa Application Centre
